There are 2 ways to getbthe most out of your grow.
1. topping will cause the lower nodes grow faster and produce more yeild but slows plant growth by as much as 2 weeks.

2. Low Stress Training (LST) you do this by bending and tying it down at a 90 deg. angle. this also causes the lower nodes to grow but is a lot less stressfull to the plant and affects growth minimally
